Embodiment Construction

[0031] An exemplary embodiment is described below with reference to the accompanying drawings. figure 1 Shown is a plan view of a cutting blade -1- according to an embodiment. The cutting blade - 1 - according to the exemplary embodiment is designed as an indexable blade. Cutting blade-1-has a top surface-2-( figure 1 shown) and the bottom surface arranged on the rear side (not shown) of the cutting blade -1-. It should be noted that the use of the references "bottom" and "top" faces assumes a certain orientation of the cutting blade, which orientation has been chosen to enable a better understanding of the following description and does not represent a limitation. In this case, the "bottom" face can of course also be arranged to the side or above the "top" face, depending on the orientation of the cutting blade.

[0032] In an exemplary embodiment, the bottom surface is designed in the same way as the top surface -2- and is arranged generally (except for the corresponding ...

Abstract

The invention relates to a cutting insert (1) for a cutting tool. In a radial direction Q, which extends in a main plane H from the cutting corner (4) to a center Z of the cutting insert (1), the following are formed in the following sequence: a falling cutting surface (8), a chip guiding stage base (9; 9a, 9b, 9c) adjacent to the cutting surface, a first chip guiding stage (11), which is adjacent to the chip guiding stage base and has a first surface (11a) rising from the chip guiding stage base and a first plateau (11b) adjacent thereto, a second chip guiding stage (12), which has a second surface (12a) rising from the first plateau (11b) and a second plateau (12b) adjacent thereto, and a third chip guiding stage (13), which has a third surface (13a) rising from the second plateau (12b) and a third plateau (13b) adjacent thereto.

Description

technical field [0001] The invention relates to a cutting blade of a cutting tool for machining workpieces. Background technique [0002] Cutting blades of cutting tools for machining workpieces are especially useful for machining metal workpieces by turning. It is known to configure such cutting inserts as indexable inserts or as indexable turning inserts, which have multiple chamfers and cutting edges which can be used in succession, for example, after the originally used chamfer or cutting edge has worn away. Cutting corners and cutting edges. In this case, the cutting blade may be configured such that both the top (or upper side) and the bottom (or underside) of the cutting blade are available for material processing. Known cutting blades generally have a geometry in which the top and bottom surfaces are constructed in the same way, and in particular have a cutting edge and a chip shape for deflecting and breaking off cut-off chips of material. [0003] In this case, ...
